Here we learn to use CAD software by ‘recreating’ a hand-drawn sketch using various tools in gCADPlus software. This step-by-step guide uses the hand-drawn landscape plan shown on the right below to recreate the design using gCADPlus software.
After playing the movie below, we suggest that you try this method on a design of your own. Since you have worked through and solved any site problem, the design for the garden (or larger space) is already set, so you can concentrate exclusively on learning to use of CAD commands. Do concentrate on the use of the draw and modifying commands.
Hand drawn sketch
This video is designed to show how to take a hand-drawn landscape plan and recreate the design in CAD software. In this exercise, the garden space is small but crammed with interest. WE first use the line tool to accurately define the boundaries of the site, the block command is used to create some large format pavers, a ‘bridge’ spans a small pond with riparian planting, a pergola is set at 45 degrees to the rectangular space and other elements are added.
When drafting by hand, it is usual to take a clean sheet of paper of appropriate size and put it on a drawing board (table) along with your scale ruler. You then think about the design, and the views, that you will use to convey the design effectively, and finally put pen to paper, selecting drafting pens of varying thickness as you work. You work with a scale ruler all the time. The opposite is true when using CAD software. Everything you draw is full-size in what is called the model or modelspace. It is only when there is a need to print the design is the designer concerned with scale.
Sheets in Australia and Europe are usually the ISO A series – A0, A1. A2 etc. The B series of sheets – B1, B2, B3, and B4 – are less commonly used and are reserved for design work in the US.
